Originally discovered by Linden in New Granada in 1842^ and 



subsequently gathered by Funck and Schlim on the eastern Cordillera, 



between Pamplona and Ocafia, at 7,000 — 8,000 feet elevation. It is 



a handsome species with pure yellow flowers, a character expressed 



by the name from Trac, " all," and y^pvaioq, " golden " ; it may be 



recognised by the delicate glaucescence that covers the green portion 



of the scape. 



On. Papilio. 



Pseudo-bulbs oval-oblong or sub-orbicular, 1| — 2 inches long, much 



compressed, wrinkled, monophyllous. Leaves elliptic-oblong, 6 — 9 inches 



long, 2 — 2| inches broad, coriaceous, dull green much mottled and 



blotched with purplish crimson which is most developed on the under 



side. Scapes 2 — 4 feet long, jointed, with a sheathing acute bract 



at each joint, terete from the base to beyond the middle, the upper 



portion flattened and ancipitous. Flowers several, produced singly by 



successive elongations of the peduncle from the joint immediately below 



the ovary, variable in size ; dorsal sepal and petals 3| — 4| inches long, 



linear, slightly dilated towards the apex, dull reddish crimson, yellowish 



green at the back ; lateral sepals oblong, sub-acuminate, decurved and 



undulate, bright chestnut-red with some narrow transverse yellow 



markings; lip three-lobed, the side lobes small, rounded, yellow spotted 



with red ; anterior lobe broadly clawed, sub-orbicular with a shallow sinus 



in the front margin, canary-yellow with a broad bright red marginal 



band ; crest a thickened obscurely three-lobed elevated plate, with two 



small protuberances on the basal side, white spotted with red. Column 



wings lacerated, much dilated below, and with two cirri above having a 



blackish gland at their tip.

Oncidium Papilio is one of the most remarkable orchids ever in- 

 troduced into European gardens, not only on account of the singular 

 appearance of its flowers but also for their scarcely less curious 

 structure, a peculiarity, however, which they share with the allied 

 species On. Kramerianum and On. Limvu'nghei already described. The 

 flowers are not produced in racemes or panicles like those of most 

 other Oncids, but in the same manner as those of the Saccolabiate
